However, the present invention is not limited to the embodiments
described below and may be embodied in various different forms. The
embodiments are provided merely to completely disclose the present
invention and completely inform one of ordinary skill in the art of
the scope of the present invention. The present invention is
defined by only the scope of the claims. Throughout the
specification, like reference numerals refer to like elements.
[0044] When it is stated that an element or a layer is "on" another
element or layer, not only being directly on another element or
layer but also interposing another layer or element therebetween
are included. On the other hand, when it is stated that an element
is "directly on" another, there is no other element or layer
interposed therebetween.
[0045] Terms which are spatially relative such as "below,"
"beneath," "lower," "above," "upper," and the like may be used to
easily describe a relationship between one element or component and
another element or component as shown in the drawings. The
spatially relative terms should be understood as terms which
include different directions of an element when the element is used
or operates, in addition to directions shown in the drawings. For
example, when an element shown in the drawing is turned upside
down, the element described as being "below" or "beneath" another
element may be disposed "above" the other element. Accordingly,
"below" which is an exemplary term may include both downward and
upward directions. The element may be arranged in another direction
such that the spatially relative terms may be understood according
to arrangement.
[0046] Although first, second, and the like are used for describing
a variety of elements, components, and/or sections, the elements,
components, and/or sections are not limited to the terms. These
terms are used for merely distinguishing one element, component, or
section from another element, component, or section. Accordingly, a
first element, a first component, or a first section which is
stated below may be a second element, a second component, or a
second section within the technical concept of the present
invention.
[0047] The terms used herein are for explaining embodiments but are
not intended to limit the present invention. Throughout the
specification, unless particularly defined otherwise, singular
forms include plural forms. The terms "comprises" and/or
"comprising" are used herein as meanings which do not exclude
presence or addition of one or more other components, stages,
operations, and/or elements in addition to stated components,
stages, operations, and/or elements.
[0048] Unless defined otherwise, all the terms (including technical
and scientific terms) have the same meaning as commonly understood
by one of ordinary skill in the art. Also, terms such as those
defined in commonly used dictionaries should not be interpreted in
an idealized or excessively formal sense unless defined
otherwise.
[0049] Hereinafter, embodiments of the present invention will be
described in detail with reference to the attached drawings. In the
description with reference to the attached drawings, irrelative to
reference numerals, like or corresponding components will be
referred to as the same reference numerals and an overlapping
description thereof will be omitted.
[0050] FIG. 1 is a side view illustrating a shoe according to some
embodiments of the present invention. FIG. 2 is a top view
illustrating an outsole of FIG. 1.
[0051] Although a training shoe is illustrated as an example in
FIG. 1, the shoe is not limited thereto. The present invention may
be applied to a variety of shapes of training shoes, for example,
running shoes, walking shoes, tennis shoes, baseball shoes,
basketball shoes, soccer shoes, and the like and may be applied to
a variety of shapes of shoes such as loafers, sneakers, straight
tip shoes, wing tip shoes, monk strap shoes, and the like.
[0052] Referring to FIGS. 1 and 2, a shoe 100 includes an outsole
110, an insole, an upper structure 120, and the like.
[0053] The outsole 110 is located at a bottom of the shoe 100 and
refers to a part which comes into contact with the ground. The
outsole 110 may be manufactured using a material such as leather,
rubber, silicone, and the like but the present invention is not
limited thereto.
[0054] Also, the outsole 110 may include, for example, a forefoot
area F, a rear foot area R, and a mid-foot area M disposed between
the forefoot area F and the rear foot area R. A ratio between the
forefoot area F, the mid-foot area M, and the rear foot area R may
be, for example, F:M:R=40:30:30.
[0055] Meanwhile, an arch area AR is a part corresponding to an
arch area of a foot. The arch area AR may be a part of the mid-foot
area M and may be disposed, for example, on an inside of the
mid-foot area M (that is, a side on which another foot is
present.
[0056] The upper structure 120 is connected and/or fixed to the
outsole 110 to define a space for inserting a foot therein. The
upper structure 120 may be formed of, for example, one or more of
leather, artificial leather, natural or synthetic fabric, a polymer
foaming material, mesh fabric, felt, a non-quilted polymer, and a
rubber material but the present invention is not limited
thereto.
[0057] The upper structure 120 includes a side surface area 122, a
shoe top area 123, and the like.
[0058] The side surface area 122 is disposed to extend along a side
surface of a foot.
[0059] The shoe top area 123 is formed corresponding to a top
surface of a foot or a foot top area. Also, a space 124 having a
lace 125 is formed on the shoe top area 123 such that the entire
size of the shoe 100 may be adjusted using the lace. That is, a
closing mechanism for allowing the shoe 100 to be well worn on a
foot is applied.
[0060] Also, a foot is inserted in the shoe 100 through an opening
126.
[0061] Meanwhile, an insole is disposed on the outsole 110. The
insole is a surface with which a foot comes into direct
contact.
[0062] Meanwhile, an embedded sensing system 105 (refer to FIG. 4)
is installed in the outsole 110 according to some embodiments of
the present invention. The sensing system 105 may sense a pressure
generated by a foot by using a plurality of sensors 201a, 202a,
203a, and 204a (refer to FIGS. 3 and 4) and may communicate with an
external device through an antenna. Since the sensing system 105 is
completely embedded in the outsole 110, the outsole 110 is
detachable from the upper structure 120 for a manufacturing process
and after-sales maintenance. A detachment method may be changed
according to a combination method (mechanical combination, chemical
combination, and the like) of the outsole 110 and the upper
structure 120.
[0063] The sensing system 105 will be described in detail with
reference to FIGS. 3 to 15.
[0064] FIGS. 3 and 4 are views illustrating positions (disposition
depths) of the plurality of sensors in the outsole of FIG. 1.
[0065] First, referring to FIG. 3, the plurality of sensors 201a,
202a, 203a, and 204a are embedded in the outsole. The plurality of
sensors 201a, 202a, 203a, and 204a may be arranged to sense
properties of each of parts of a user's foot (that is, toes, a ball
of the foot, a heel of the foot, and the like).
[0066] For example, a first sensor 201a and a third sensor 203a may
correspond to the ball of the foot, a second sensor 202a may
correspond to the toes of the foot (particularly, a big toe), and a
fourth sensor 204a may correspond to the heel of the foot. Here,
the number and positions of the plurality of sensors 201a, 202a,
203a, and 204a may change according to a design. For example, the
number of sensors 201a, 202a, 203a, and 204a may be five or more or
three or less. Also, for example, the sensor 202a may be disposed
in a position corresponding to a second toe or a third toe instead
of the big toe, and for example, the sensors 201a and 203a may be
arranged in positions corresponding to the mid-foot area. Also, the
plurality of sensors 201a, 202a, 203a, and 204a may be film-type
pressure sensors. However, depending on a design, other types of
sensors may be arranged.
[0067] In the shoe according to some embodiments of the present
invention, at least two of the plurality of sensors 201a, 202a,
203a, and 204a may be disposed at different depths.
[0068] In detail, closer to a front end 110a of the outsole 110,
the sensors 201a, 202a, 203a, and 204a may be embedded to be closer
to (shallower with respect to) a top surface 110u of the outsole
110. Also, toward the rear end 110b of the outsole 110, the sensors
201a, 202a, 203a, and 204a may be embedded to be farther from
(deeper with respect to) the top surface 110u of the outsole
110.
[0069] Referring to FIGS. 3 and 4, the second sensor 202a may be
installed at a disposition depth Ta, the first sensor 201a and the
third sensor 203a may be installed at a disposition depth Tb, and
the fourth sensor 204a may be installed at a disposition depth Tc.
Here, the disposition depths Ta, Tb, and Tc refer to depths from
the top surface 110u of the outsole 110.
[0070] The second sensor 202a is closer to the front end 110a of
the outsole 110 than the fourth sensor 204a (that is, far from the
rear end 110b of the outsole 110). Accordingly, the second sensor
202a is disposed to be shallower than the fourth sensor 204a. That
is, the disposition depth Ta of the second sensor 202a is shallow
in comparison to the disposition depth Tc of the fourth sensor
204a.
[0071] Also, the first sensor 201a and the third sensor 203a are
farther from the front end 110a of the outsole 110 than the second
sensor 202a and are farther from the rear end 110b of the outsole
110 than the fourth sensor 204a. Accordingly, the first sensor 201a
and the third sensor 203a may be disposed to be deeper than the
second sensor 202a and disposed to be shallower than the fourth
sensor 204a. That is, the disposition depth Tb of the first sensor
201a and the third sensor 203a are deeper than the disposition
depth Ta of the second sensor 202a and are shallower than the
disposition depth Tc of the fourth sensor 204a.
[0072] Meanwhile, the first sensor 201a and the third sensor 203a
are shown as being disposed at the same depth Tb in FIG. 4 but are
not limited thereto. For example, according to a distance from the
front end 110a of the outsole 110, a disposition depth of the first
sensor 201a and a third disposition depth of the third sensor 203a
may differ.
[0073] Also, the first sensor 201a to the fourth sensor 204a are
embedded at depths of 10% or more and 70% or less from the top
surface 110u of the outsole. Here, a depth shown as % is indicated
on the basis of a thickness T of a thickest part (for example, the
heel) of the outsole 110.
[0074] When the first sensor 201a to the fourth sensor 204a are
embedded at depths of 0% or more and less than 10% from the top
surface 110u of the outsole, the disposition depths Ta, Tb, and Tc
are arranged too shallowly such that a consistent pressure value
(or sensing value) is not extracted. Also, a pressure value is not
extracted to be as much as an actually applied force. This will be
described below in detail with reference to FIG. 5. Here, 0% means
that a sensor is disposed to be exposed to the top surface 110u of
the outsole 110.
[0075] Also, when the first sensor 201a to the fourth sensor 204a
are embedded at depths of more than 70% and 100% or less from the
top surface 110u of the outsole, the disposition depths Ta, Tb, and
Tc are arranged too deep such that it is very difficult to obtain a
pressure value with respect to a light weight. Also, when the
sensors 201a, 202a, 203a, and 204a are too close to a bottom
surface of the outsole 110, durability of the sensors 201a, 202a,
203a, and 204a decreases greatly. It will be described below in
detail with reference to FIG. 6. Here, 100% means that a sensor is
disposed to be exposed to the bottom surface of the outsole
110.
[0076] Accordingly, when the first sensor 201a to the fourth sensor
204a are embedded at depths of 10% or more and 70% or less from the
top surface 110u of the outsole, it is possible to obtain an
effective pressure value. It will be described below in detail with
reference to FIG. 7.
[0077] The inventors of the present invention have derived a result
as follows through a plurality of experiments. In a range of 10% or
more and 70% or less, it is possible to obtain a most effective
pressure value within a range of 10% or more and 40% or less, to
obtain a considerably effective pressure value within a range of
more than 40% and 60% or less, and to obtain an effective pressure
value within a range of more than 60% and 70% or less. That is,
pressure values are precisely obtained in an order of the range of
10% or more and 40% or less, the range of more than 40% and 60% or
less, and the range of more than 60% and 70% or less.
[0078] In the range of 10% or more and 40% or less, the second
sensor 202a may be installed at the disposition depth Ta of 10% or
more and 20% or less, the first sensor 201a and the third sensor
203a may be installed at the disposition depth Tb of more than 20%
and 30% or less, and the fourth sensor 204a may be installed at the
disposition depth Tc of more than 30% and 40% or less. It will be
described below in detail with reference to FIG. 8.
[0079] Meanwhile, the disposition depths Ta and Tb of the second
sensor 202a and the first and third sensors 201a and 203a have been
described as differing from each other but are not limited thereto.
That is, depending on a design type, the disposition depths Ta and
Tb may be the same. An exemplary embodiment thereof will be
described in detail with reference to FIGS. 9 to 12. In
consideration of a shoe shape and a foot shape, when the
disposition depths Ta and Tb are the same, it is possible to easily
embody the shoe.
[0080] FIGS. 5 to 7 are views illustrating a relationship between a
disposition depth and sensitivity of a sensor. FIGS. 5 to 7
illustrate test results. In FIGS. 5 to 7, an X-axis indicates time
t and a Y-axis indicates a weight kg.
[0081] Test conditions of FIG. 5 are as follows. The first sensor
201a to the fourth sensor 204a were embedded at a depth of 0% or
more and less than 10%. After the first sensor 201a to the fourth
sensor 204a were embedded, pressure values of the first sensor 201a
to the fourth sensor 204a during three consecutive walking cycles
WK1 to WK3 were checked. During the three consecutive walking
cycles WK1 to WK3, a maximum force of 21 kg was applied to the
fourth sensor 204a, a maximum force of 15 kg was applied to the
first sensor 201a and the third sensor 203a, and a maximum force of
8 kg was applied to the second sensor 202a.
[0082] As shown by a reference numeral N, it may be seen that
although the maximum force of 21 kg was applied to the fourth
sensor 204a, only about 15 kg was sensed. That is, it may be seen
that the pressure value did not reach a level of force which was
actually applied. Also, it may be seen that consistency among the
pressure values of the first sensor 201a to the fourth sensor 204a
was low.
[0083] Test conditions of FIG. 6 are as follows. The first sensor
201a to the fourth sensor 204a were embedded at a depth of more
than 70% and 100% or less. After the first sensor 201a to the
fourth sensor 204a were embedded, pressure values of the first
sensor 201a to the fourth sensor 204a during three consecutive
walking cycles WK1 to WK3 were checked. During the three
consecutive walking cycles WK1 to WK3, a maximum force of 21 kg was
applied to the fourth sensor 204a, a maximum force of 15 kg was
applied to the first sensor 201a and the third sensor 203a, and a
maximum force of 8 kg was applied to the second sensor 202a.
[0084] As shown by a reference numeral L, it may be seen that a
sensing time (length) of the fourth sensor 204a was considerably
shorter than a time for which a force was actually applied. It may
be seen that the pressure values of the first sensor 201a and the
third sensor 203a were not same. Although not additionally shown in
the drawing, during the test, a plurality of cases were found in
which sensing times (lengths) of the first sensor 201a and the
third sensor 203a become considerably shorter.
[0085] Test conditions of FIG. 7 are as follows. The first sensor
201a to the fourth sensor 204a were embedded at a depth of 10% or
more and 70% or less. After the first sensor 201a to the fourth
sensor 204a were embedded, pressure values of the first sensor 201a
to the fourth sensor 204a during three consecutive walking cycles
WK1 to WK3 were checked. During the three consecutive walking
cycles WK1 to WK3, a maximum force of 21 kg was applied to the
fourth sensor 204a, a maximum force of 15 kg was applied to the
first sensor 201a and the third sensor 203a, and a maximum force of
8 kg was applied to the second sensor 202a.
[0086] As shown by a reference numeral M1, it may be seen that the
fourth sensor 204a sensed the pressure value to be as much as the
applied force. The other sensors 201a, 201b, and 201c also sensed
the pressure values to be as much as the applied forces. As shown
by a reference numeral M2, it may be seen that the first sensor
201a and the third sensor 203a had sensing times (lengths) which
were the same as actually applied times. As shown by a reference
numeral M1, it may be seen that the fourth sensor 204a also had an
adequate sensing time (length).
[0087] FIG. 8 is a graph illustrating a relationship between a
disposition depth and sensitivity of a sensor. FIG. 8 is a graph
for detecting optimal values of the disposition depths of the first
sensor 201a to the fourth sensor 204a. In FIG. 8, an X-axis
indicates a voltage mV sensed by a sensor, and a Y-axis indicates a
weight kg.
[0088] Referring to FIG. 8, a voltage, which was measured by a
sensor while the sensor was disposed at the disposition depth Ta of
10% or more and 20% or less and then a weight kg was changed, is
recorded as a quadrangular dot (or an orange-colored dot) d1. The
voltage was measured a plurality of times for each weight kg.
[0089] A voltage, which was measured by the sensor while the sensor
was disposed at the disposition depth Tb of more than 20% and 30%
or less and then the weight kg was changed, is recorded as a
circular dot (or a gray-colored dot) d2. The voltage was measured a
plurality of times for each weight kg.
[0090] A voltage, which was measured by the sensor while the sensor
was disposed at the disposition depth Tc of more than 30% and 40%
or less and then the weight kg was changed, is recorded as a
triangular dot (or a sky blue-colored dot) d3. The voltage was
measured a plurality of times for each weight kg.
[0091] A line g1 connects average values of the triangular dots d3,
and a line g2 connects averages values of the quadrangular dots
d1.
[0092] First, when seeing the quadrangular dots d1 and the
triangular dots d3, it may be seen that the quadrangular dots d1
are marked at a maximum of about 55 kg and the triangular dots d3
are marked at a maximum of about 68 kg. That is, it may be seen
that a heavier weight (force) is measurable at the deep disposition
depth Tc and a relatively lighter weight (force) is measurable at
the shallow disposition depth Ta (refer to the quadrangular dots
d1). That is, it may be seen that a heavier weight (force) is
measurable when a disposition depth becomes deeper.
[0093] Additionally, when the line g1 and the line g2 in a first
weight section f1 are compared with each other, it may be seen that
the line g2 is more straight, or linear, than the line g1.
[0094] On the other hand, when the line g1 and the line g2 are
compared with each other in a second weight section f2, which is
heavier than the first weight section f1, it may be seen that the
line g1 has more straightness or linearity than the line g2. That
is, it may be seen that linearity is shown with respect to a
heavier weight (force) as a disposition depth becomes deeper.
[0095] That is, it may be seen that linearity is shown with respect
to a lighter weight (force) as a disposition depth becomes
shallower.
[0096] Accordingly, the fourth sensor 204a for measuring a heavier
weight is disposed deeper than the first sensor 201a to the third
sensor 203a. The second sensor 202a for measuring a lighter weight
is disposed shallower than the first sensor 201a, the third sensor
203a, and the fourth sensor 204a. As a result thereof, the second
sensor 202a may be installed at the disposition depth Ta of 10% or
more and 20% or less, the first sensor 201a and the third sensor
203a may be installed at the disposition depth Tb of more than 20%
and 30% or less, and the fourth sensor 204a may be installed at the
disposition depth Tc of more than 30% and 40% or less.
[0097] Embodiments of the sensing system will be described with
reference to FIGS. 9 to 12. FIGS. 9 to 12 exemplarily illustrate a
case in which the disposition depths Ta and Tb of the second sensor
202a and the first and third sensors 201a and 203a are the
same.
[0098] FIG. 9 is a view illustrating a sensing system which is
completely embedded in the outsole of FIG. 1. FIG. 10 illustrates a
first flexible circuit board of FIG. 9. FIG. 11 illustrates a
second flexible circuit board of FIG. 9. FIG. 12 is a
cross-sectional view taken along a line B-B of FIG. 10.
[0099] First, referring to FIGS. 9 to 11, the sensing system 105
may include a first flexible circuit board 200, a second flexible
circuit board 200a, a control module 400, an antenna 500, and the
like.
[0100] The first flexible circuit board 200 and the second flexible
circuit board 200a are separated from each other. For example, the
first flexible circuit board 200 may be connected to a top surface
of the control module 400 and the second flexible circuit board
200a may be connected to a rear surface of the control module 400
but the present invention is not limited thereto.
[0101] The first flexible circuit board 200 includes a plurality of
sensing areas 201, 202, and 203, in which the plurality of sensors
201a, 202a, and 203a are installable, and wires 211, 212, and 213,
which are connected to the plurality of sensors. The second
flexible circuit board 200a includes a plurality of sensing areas
204 in which at least one sensor 204a is installable and a wire 214
is connected to the at least one sensor.
[0102] Among the sensing areas 201, 202, 203, and 204, a first
sensing area 201 and a third sensing area 203 may correspond to a
ball of a foot, the second sensing area 202 may correspond to a big
toe of the foot, and the fourth sensing area 204 may correspond to
a heel of the foot. Here, the number and positions of the plurality
of sensing areas 201, 202, 203, and 204 may change according to a
design. For example, the number of sensing areas 201, 202, 203, and
204 may be five or more or three or less. Also, the sensing areas
201, 202, 203, and 204 may be arranged in positions corresponding
to a second toe or a third toe instead of the big toe and may
correspond to a mid-foot area. Hereinafter, one of the sensors
201a, 202a, 203a, and 204a is described as being disposed in each
of the sensing areas 201, 202, 203, and 204 but the present
invention is not limited thereto. That is, instead of one sensor,
two or more sensors may be arranged in each of the sensing areas
201, 202, 203, and 204. Also, in the shoe according to some
embodiments of the present invention, the sensors 201a, 202a, 203a,
and 204a may be film-type pressure sensors. Depending on a design,
another shape of sensors may be disposed.
[0103] Disposition depths of the plurality of sensors 201a, 202a,
203a, and 204a may be positions which have been described with
reference to FIGS. 3 to 8. The plurality of sensors 201a, 202a,
203a, and 204a are embedded at depths of 10% or more and 70% or
less. For example, the second sensor 202a may be installed at the
disposition depth Ta of 10% or more and 20% or less, the first
sensor 201a and the third sensor 203a may be installed at the
disposition depth Tb of more than 20% and 30% or less, and the
fourth sensor 204a may be installed at the disposition depth Tc of
more than 30% and 40% or less.
[0104] The wires 211, 212, 213, and 214 may start from a connection
area 220 and may diverge toward the sensing areas 201, 202, 203,
and 204.
[0105] For example, the wires 211, 212, 213, and 214, as shown in
the drawings, may have a reverse C shape or a right side of
brackets, that is, a "1" shape. That is, the wires 211, 212, 213,
and 214 may start from the connection area 220 and deviate from an
outside of the shoe to reach the sensing areas 201, 202, 203, and
204. Due to the above shape, the wires 211, 212, 213, and 214 may
be stably collected in the connection area 220, and the wires 211,
212, 213, and 214 may be prevented from being broken.
[0106] Here, the wires 211, 212, 213, and 214 may be electrically
connected to the control module 400 through the connection area
220.
[0107] Although the connection area 220 will be described below,
the connection area 220 may be formed inside the arch area AR of
the shoe.
[0108] Also, as shown in FIG. 12, for example, the sensor 201a may
be disposed in a downward direction DS of, for example, the sensing
area 201 of the first flexible circuit board 200. For example, a
wire 201b from the sensor 201a may be directly connected to the
wire 211 of a wire area. The wires 201b and 211 may be arranged in
the downward direction DS. Here, an upward direction US is a
direction in which a foot of a user of the shoe 100 is present and
the downward direction DS is opposite to the upward direction US
and toward the ground. As described above, the wires 201b and 211
and the sensor 201a face the downward direction DS. Additionally,
since a support plate is present below the first flexible circuit
board 200, durability of the wires 201b and 211 and the sensor 201a
may increase.
[0109] Since the sensing system 105 is formed to be completely
embedded in the outsole 110, for example, when the wires 201b and
211 face the upward direction US, the wires 201b and 211 come into
direct contact with the outsole 110. In this case, friction occurs
between the wires 201b and 211 and the outsole 110 such that the
wires 201b and 211 may be easily broken. On the other hand, when
the wires 201b and 211 face the support plate 300, a possibility,
in which a phenomenon of being broken occurs, decreases.
[0110] For example, a disposition direction of the sensor 201a of
the second flexible circuit board 200a may be the same as a
disposition direction of, for example, the sensor 204a of the first
flexible circuit board 200. That is, for example, the sensor 204a
may be disposed in the downward direction DS of, for example, the
sensing area 204 of the second flexible circuit board 200a.
[0111] Although not particularly shown in the drawing, support
plates may be disposed below the first flexible circuit board 200
and the second flexible circuit board 200a. The support plates
increase sensing sensitivities of the sensors 201a, 202a, 203a, and
204a.
[0112] When a user walks, runs, or exercises, a foot of the user
steps on, for example, the sensor 201a (the film-type pressure
sensor). However, since the sensor 201a is embedded in the outsole
110, when the support plate is not present, the sensor 201a may
directly push the outsole 110 when the foot of the user steps on
the sensor 201a. However, when the outsole 110 is formed of a soft
material capable of preventing a shock (for example, rubber,
silicone, and the like), the sensor 20a meets the soft material.
Accordingly, the sensing sensitivity of the sensor 201a decreases.
Accordingly, below the sensing areas 201, 202, 203, and 204 of the
flexible circuit board 200, the support plate formed of a material
having higher strength than strength of the outsole 110 is
installed. Accordingly, when the foot of the user pushes the sensor
201a, the sensor 201a comes into direct contact with the support
plate instead of the soft material. Accordingly, the sensing
sensitivity of the sensor 201a may increase. The support plate may
have strength higher than strength of the flexible circuit board
200.
[0113] FIG. 13 is a view illustrating the control module and the
antenna of FIG. 9.
[0114] Referring to FIG. 13, the control module 400 may be disposed
to correspond to the inside of the arch area AR.
[0115] As described above, the arch area AR may be a part
corresponding to an arch area of the foot. The arch of the foot
performs a function of stably maintaining posture while standing, a
function of absorbing a shock by sensing an excessive force of a
weight, and the like. The arch of the foot is a position which is a
dented position and receives a least amount of weight. Accordingly,
in the shoe according to some embodiments of the present invention,
the control module 400 is disposed on an inside IS1 of the arch
area AR such that durability of the control module 400 may be
provided.
[0116] As described above, the outsole 110 includes the forefoot
area F, the mid-foot area M, and the rear foot area R. In detail,
the control module 400 may be disposed on the inside IS1 on the
basis of a first virtual line VL1 which connects both ends of the
outsole 110 in a longitudinal direction thereof in the mid-foot
area M.
[0117] Also, the control module 400 may be mounted in a first
trench 112 of the outsole 110. The control module 400 may include a
circuit board connected to the wires 211, 212, 213, and 214 through
the connection area 220 (refer to FIG. 9) and at least one chip
and/or passive element installed on the circuit board. The control
module 400 may be in, for example, a case. A bottom surface of the
case may have a curved shape to surround the circuit board. The
curved shape may protect the circuit board, the chip, the passive
element, and the like from shocks.
[0118] On the other hand, the antenna 500 may be disposed on an
outside OS1 on the basis of the first virtual line VL1. The antenna
500 may be mounted in a second trench 114 of the outsole 110. The
control module 400 and the antenna 500 are connected through a wire
450, and an additional trench on which the wire 450 is mounted may
be present in the outsole 110.
[0119] Here, depending on a position of the antenna 500 in the
outsole 110, emissivity (or an emission rate) of the antenna 500
may change.
[0120] As the antenna 500 moves toward the inside IS1, since a
signal generated by the control module 400 is hidden by the
outsole, the signal is hardly transmitted to an external device. On
the other hand, as the antenna 500 becomes closer to the outside,
the signal generated by the control module 400 is easily
transmitted to the external device. Also, as the antenna 500
becomes closer to the innermost side other than the outermost side,
emissivity may decrease. As an example, a left foot is located in
an inward direction of a right foot. Accordingly, the presence and
movement of the left foot may decrease the emissivity of the signal
generated by the control module 400.
[0121] Accordingly, in the shoe according to some embodiments of
the present invention, the antenna 500 is disposed on the outside
OS1 of the first virtual line VL1 and disposed to be maximally
close to the outermost side. Simply in order to completely embed
the antenna 500 in the outsole 110, for example, the antenna 500
may be disposed inward 2 mm to 5 mm from the outermost side.
[0122] FIG. 14 is a view illustrating the control module and the
antenna of FIG. 9. For convenience of description, only points
different from FIG. 13 will be described.
[0123] Referring to FIG. 14, the entire control module 400 may not
be in the arch area AR. For example, 50% or more of the control
module 400 may be disposed in the arch area AR. As shown in the
drawing, 60% or more, in more detail, 70% or more, of the control
module 400 may be disposed in the arch area AR.
[0124] FIG. 15 is a view illustrating the control module and the
antenna of FIG. 9.
[0125] Referring to FIG. 15, a position of the control module 400
will be described in another way as follows. That is, the control
module 400 may be disposed in the mid-foot area on an inside 102 on
the basis of a second virtual line VL2 which connects a second toe
to an end of a foot, and the antenna 500 may be disposed on an
outside OS2 on the basis of the second virtual line VL2.
[0126] FIG. 16 is a view illustrating a relationship between the
shoe and an external device according to some embodiments of the
present invention. A configuration of the shoe (the control module
400) and a configuration of the external device shown in FIG. 16
are examples and the present invention is not limited thereto.
[0127] Referring to FIG. 16, the control module 400 may include an
input module 401, a processor 402, a memory 403, a power supply
module 404, a transmission and reception module 405, and the like.
Each module therein may be separately housed or some modules may be
housed as one.
[0128] The input module 401 receives a plurality of sensing values
provided by the plurality of sensors 201a to 204a. As described
above, the plurality of sensors 201a to 204a may be film-type
pressure sensors.
[0129] The processor 402 processes the plurality of sensing values
which are input thereto. For example, the processor 402 may convert
the plurality of sensing values into a data format adequate for
being stored in the memory 403 or may match measuring times with
the sensing values. The processor 402 controls the memory 403, the
power supply module 404, and the transmission and reception module
405.
[0130] The memory 403 may store the plurality of sensing values
according to a time or may store signals processed by the processor
402.
[0131] The power supply module 404 may supply power to the
processor 402, the memory 403, the transmission and reception
module 405, and the like.
[0132] Unlike the drawing, an additional sensor (not shown) may be
installed in the shoe 100. For example, the additional sensor may
sense pedometer type velocity and/or distance information, other
velocity and/or distance data sensor information, a temperature, an
altitude, atmospheric pressure, humidity, global positioning system
(GPS) data, accelerator type output or data, a heat rate, a pulse,
a blood pressure, electrocardiogram (EKG) data,
electroencephalogram (EEG) data, angular orientation (a
gyroscope-based sensor and the like), data related to a change in
the angular orientation, and the like. Otherwise, the additional
sensor may sense data or information related to a wide variety of
different types of parameters such as use of a shoe product or
physical or biological data related to a user.
[0133] The control module 400 may communicate with an external
device 900 with respect to sensing values or processed data through
the transmission and reception module 405.
[0134] The external device 900 may be a computing system (for
example, a desktop personal computer (PC), a smart phone, a tablet,
a pad, a server, and the like) but a type thereof is not limited.
The external device 900 may include an input module 901, a
processor 902, a memory 903, a power supply module 904, a
transmission and reception module 905, a display module 906, and
the like.
[0135] The input module 901 may receive instructions/data and the
like from a user.
[0136] The transmission and reception module 905 may receive
sensing values or processed data from the shoe 100. Also,
signals/data may be provided by other components in addition to the
shoe 100.
[0137] The processor 902 processes the signals/data provided from
the transmission and reception module 905. For example, depending
on time, an operation of matching the sensing values with video
signals (for example, video signals obtained by measuring a
movement (motion) performed by using a camera while the shoe is
being worn) may be performed.
[0138] Also, the processor 902 may generate a variety of
calculation values on the basis of the sensing values provided by
the plurality of sensors 201a, 202a, 203a, and 204a. Also, the
processor 902 matches the calculation values with the video signals
according to a time. An image displayed by the matched calculation
values and video signals will be described below with reference to
FIGS. 21 to 25.
[0139] R1, R2, R3, and R4 refer to sensing values sensed by the
sensors 201a, 202a, 203a, and 204a installed in the sensing areas
201, 202, 203, and 204 (refer to FIG. 2) of a right shoe. Likewise,
L1, L2, L3, and L4 refer to sensing values sensed by sensors
installed in sensing areas of a left shoe. For example, Ri
(i=1,2,3,4) and Li (i=1,2,3,4) are sensing values obtained by the
sensors installed in positions which are symmetrical to each
other.
[0140] Examples of the calculation values generated by the
processor 902 are as follows.
RF=R1+R2+R3
RB=R4
RA=RF+RB=R1+R2+R3+R4
LF=L1+L2+L3
LB=L4
LA=LF+LB=L1+L2+L3+L4
[0141] Here, RF is a sum of sensing values sensed at a front of the
right shoe, and RB is a sum of sensing values sensed at a back of
the right shoe. RA is a sum of sensing values sensed in an entirety
of the right shoe.
[0142] Here, LF is a sum of sensing values sensed at a front of the
left shoe, and LB is a sum of sensing values sensed at a back of
the left shoe. LA is a sum of sensing values sensed in an entirety
of the left shoe.
FRT=RF+LF=R1+R2+R3+L1+L2+L3
BCK=RB+LB=R4+L4
[0143] Here, FRT is a sum of sensing values sensed at the fronts of
the left shoe and the right shoe, and BCK indicates a sum of
sensing values sensed at the backs of the left shoe and the right
shoe.
[0144] Meanwhile, the above-described calculation values RF, RB,
RA, LF, LB, LA, FRT, and BCK are described as being calculated
using a simple arithmetic sum but the present invention is not
limited thereto. That is, a weighted sum may be used. For example,
more weights may be given to R1 and L1 than R3 and L3 so as to
calculate RF, RB, RA, LF, LB, LA, FRT, BCK, and the like.
[0145] Also, the processor 902 may calculate a variety of ratio
forms of calculation values R_RF_LF1, R_RF_LF2, R_RB_LB1, R_RB_LB2,
R_RA_LA1 R_RA_LA2, R_FRT_BCK1, R_FRT_BCK2 by using the calculated
calculation values RF, RB, RA, LF, LB, LA, FRT, BCK, and the
like.
R_RF_LF1=RF:LF
R_RF_LF2=(RF/FRT)*100:(LF/FRT)*100
R_RB_LB1=RB:LB
R_RB_LB2=(RB/BCK)*100:(LB/BCK)*100
R_RA_LA1=RA:LA
R_RA_LA2=(RA/(RA+LA))*100:(LA/(RA+LA))*100
R_FRT_BCK1=FRT:BCK
R_FRT_BCK2=(FRT(FRT+BCK))*100:(BCK(FRT+BCK))*100
[0146] Here, R_RF_LF1 is a ratio between a sensing value sensed at
a front of a right shoe and a sensing value sensed at a front of a
left shoe. R_RF_LF2 is a value obtained by converting R_RF_LF1 on
the basis of 100%. For example, when R_RF_LF1=33:11 (or shown as
3:1), it may become R_RF_LF1=75:25.
[0147] Similarly, R_RB_LB1 is a ratio between a sensing value
sensed at a back of a right shoe and a sensing value sensed at a
back of a left shoe. R_RB_LB2 is a value obtained by converting
R_RB_LB1 on the basis of 100%.
[0148] Similarly, R_RA_LA1 is a ratio between a sum of sensing
values sensed at a right shoe and a sum of sensing values sensed at
a left shoe. R_RA_LA2 is a value obtained by converting R_RA_LA1 on
the basis of 100%.
[0149] Similarly, R_FRT_BCK1 is a ratio between a sum of sensing
values sensed at fronts of right/left shoes and a sum of sensing
values sensed at backs of right/left shoes. R_FRT_BCK2 is a value
obtained by converting R_FRT_BCK1 on the basis of 100%.
[0150] The calculation values which are generated as described
above may be externally shown through the display module 906. The
generated calculation values may be shown as is or may be shown as
a variety of forms of graphics (or in a user interface (UI) form)
through the display module 906. An example of the UI form will be
described below in detail with reference to FIGS. 17 to 25.
[0151] Also, the processor 902 controls the memory 903, the power
supply module 904, the transmission and reception module 905, the
display module 906, and the like. The memory 903 stores
signals/data provided by the processor 902. The power supply module
904 supplies power to the processor 902, the memory 903, the
display module 906, and the like. The display module 906 externally
shows signals/data generated by the processor 902.
[0152] FIGS. 17 to 20 are exemplary graphs displaying generated
calculation values. FIGS. 17 to 20 merely illustrate examples of
displaying the generated calculation values, and the calculation
values may be embodied in another form.
[0153] FIG. 17 is a graph illustrating a left shoe model, a right
shoe model, and a center of weight (COW) at the same time.
[0154] Referring to FIG. 17, the sensing values L1, L2, L3, and L4
sensed by the plurality of sensors installed in the left shoe are
intuitively shown in a left shoe model 636. In a right shoe model
635, the sensing values R1, R2, R3, and R4 sensed by the plurality
of sensors installed in the right shoe are intuitively shown. High
and low sensing values may be shown in a variety of methods such as
color/brightness/chroma/isobaric line and the like.
[0155] Reference numerals 631 and 632 refer to R_FRT_BCK2. That is,
sensing values 631 sensed at fronts of right/left shoes are 29, and
sensing values 632 sensed at backs of right/left shoes are 71.
[0156] Reference numerals 633 and 634 refer to R_RA_LA2. That is,
the sensing value 633 sensed at a left shoe is 67, and the sensing
value 634 sensed at a right shoe is 33.
[0157] Also, COW indicates where a center of gravity is for a user
who wears shoes. That is, COW may be shown by marking a point 639
on a virtual plane 638. COW may be determined using a value of
R_FRT_BCK2, R_RA_LA2.
[0158] FIG. 18 is a screen for displaying a change of a calculation
value R_RA_LA2 according to a time.
[0159] Referring to FIG. 18, the change of the calculation value
R_RA_LA2 according to a time is shown as a line 663 in which
rocking leftward and rightward may be seen.
[0160] Reference numerals 661 and 662 show the calculation values
R_RA_LA2 as numbers. The sensing value 662 sensed at a left shoe is
43, the sensing value 661 sensed at a right shoe is 57. The
calculation value R_RA_LA2 at a position on a line 663 which is
designated by a user is shown as the reference numerals 661 and
662. When the user does not designate the position on the line 663,
a calculation value R_RA_LA2 at a current time (or a current state)
may be shown or a calculation value R_RA_LA2 at a final use time of
the shoe may be shown. Otherwise, according to a selection of the
user, a number which indicates the calculation value R_RA_LA2 may
not be shown (that is, may be optional).
[0161] FIG. 19 is a screen for displaying a change of a calculation
value R_FRT_BCK2 according to a time.
[0162] Referring to FIG. 19, the change of the calculation value
R_RA_LA2 according to a change in time is shown as a line 668 in
which rocking leftward and rightward according to a time may be
seen.
[0163] Reference numerals 666 and 667 show the calculation values
R_FRT_BCK2 as numbers. The sensing value 666 sensed at fronts of
right/left shoes is 57, the sensing value 667 sensed at backs of
right/left shoes is 43. The calculation value R_FRT_BCK2 at a
position on a line 668 which is designated by a user is shown as
the reference numerals 666 and 667. When the user does not
designate the position on the line 668, a calculation value
R_FRT_BCK2 at a current time (or a current state) may be shown or a
calculation value R_FRT_BCK2 at a final use time of the shoe may be
shown. Otherwise, according to a selection of the user, a number
which indicates the calculation value R_FRT_BCK2 may not be shown
(that is, may be optional).
[0164] FIG. 20 is a screen for displaying a change of calculation
values RA and LA according to a time.
[0165] Referring to FIG. 20, changes in the calculation values RA
and LA according to a time are shown as lines 671 and 672 such that
it may be seen whether bottoms of the right/left shoes come into
contact with the ground according to a time.
[0166] The contact of the right shoe may be seen through the
reference numeral 671, and the contact of the left shoe may be seen
through the reference numeral 672.
[0167] FIG. 21 is another display screen for illustrating a
generated calculated value and a motion image of a user at the same
time. FIG. 22 is an example of a display screen of FIG. 21.
[0168] Referring to FIGS. 21 and 22, after a user wears shoes
according to the above-described some embodiments of the present
invention, a motion image of the user (walking, running, playing
golf, playing baseball, fitness, and the like) is captured. During
image-capturing, a plurality of sensing values are sensed by a
plurality of sensors in the shoes. At the same as image capturing
or after image capturing is finished, at least one calculation
value is generated by using the plurality of sensing values.
[0169] The motion image of the user may be displayed with at least
one sensing value or at least one calculation value.
[0170] In detail, for example, the display screen may include a
first screen 620, a second screen 630, a third screen 640, a first
control area 610, and a second control area 650.
[0171] In the first screen 620, the motion image of the user is
displayed. The motion image of the user may be a pre-captured image
or an image which is being captured.
[0172] In the second screen 630 and the third screen 640, the
sensing values or the calculation values obtained from the shoes of
the user in the motion image are displayed.
[0173] For example, in the second screen 630, a left shoe model, a
right shoe model, and COW may be displayed at the same time (refer
to FIG. 17).
[0174] In the third screen 640, a change of a calculation value
R_RA_LA2, a calculation value R_FRT_BCK2, or calculation values RA
and LA is displayed (refer to FIGS. 18, 19, and 20). According to a
selection of the user, one of the calculation value R_RA_LA2, the
calculation value R_FRT_BCK2, and the calculation values RA and LA
may be shown. For example, when a conversion key 641 in the third
screen 640 of FIG. 22 is pushed, for example, the third screen 649
may be converted from the screen of FIG. 18 into the screen of FIG.
19. When the conversion key 641 is pushed again, the third screen
640 may be converted from the screen of FIG. 19 into the screen of
FIG. 20.
[0175] Otherwise, at least one of the above-described variety of
calculations values RF, RB, RA, LF, LB, LA, FRT, BCK, R_RF_LF1,
R_RF_LF2, R_RB_LB1, R_RB_LB2, R_RA_LA1, R_RA_LA2, R_FRT_BCK1, and
R_FRT_BCK2 may be displayed.
[0176] Meanwhile, when a section repeating key 644 of FIG. 22 is
pushed, images of a motion and calculation values which are
displayed in the first screen 620 to the third screen 640 are
repeated section by section.
[0177] Meanwhile, the first control area 610 may include a
video-recording key/sound-recording key 601, a share key 602, and a
comparison key 603.
[0178] The user may share captured images, sensing values,
calculation values, and the like with other people (for example, an
instructor, a trainer, and the like) by pushing the share key
602.
[0179] Sequentially, the instructor (or the trainer and the like)
may correct a posture and the like of the user simultaneously while
watching the captured image, the sensing values, and the
calculation values. In detail, the instructor may push the
video-recording key/sound-recording key 601 and then may verbally
explain well-executed points, poorly-executed points, points for
correction, and the like while also writing by hand on the display
module. In FIG. 22, for example, it is shown that the instructor
handwrites evaluation (GOOD!), an angle (108.degree.), and the
like. The explanation may be recorded as video/sound files. The
instructor may give the user feedback by pushing the share key
602.
[0180] Also, when the user pushes the comparison key 603, the
captured images, the sensing values, and the calculation values may
be compared with captured images, sensing values, and calculation
values of another user. Here, the other user may be an
acquaintance, such as a user's friend and the like. Otherwise, the
other user may be a professional player or the instructor
(trainer). The captured images, the sensing values, the calculation
values, and the like of the other user are prestored in a server or
a storage device. When the user pushes the comparison key 603, the
captured images, the sensing values, the calculation values, and
the like of the other user may be provided from the server or the
storage device. An exemplary image after the comparison key 603 is
pushed is like FIG. 23.
[0181] FIG. 23 is a display screen for illustrating compared images
of the user and another user.
[0182] Referring to FIG. 23, a fourth screen 720 and a fifth screen
730 are displayed at the same time. For example, an image of the
user may be displayed in the fourth screen 720, and an image of the
other user (professional player, instructor (trainer), and the
like) may be displayed in the fifth screen 730.
[0183] In a sixth screen 770, sensing values or calculation values
of the user of the fourth screen 720 may be displayed.
[0184] In a seventh screen 780, sensing values or calculation
values of the user of the fifth screen 730 may be displayed.
[0185] A reference numeral 701 is a video-recording
key/sound-recording key. A reference numeral 705 may be a
handwriting key. When the user or another user (instructor,
trainer, and the like) pushes the handwriting key 705, evaluation,
explanation, and the like may be written on the screen of the
display module.
[0186] Here, a reference numeral 790 is a combination key. When the
user pushes the combination key 790, the fourth screen 720 is
combined with the fifth screen 730 and the sixth screen 770 is
combined with the seventh screen 780. In detail, before the
combination key 790 is pushed, the fourth screen 720 and the fifth
screen 730 operate separately. That is, even when an image
displayed on the fourth screen 720 is moved back by a time t1, an
image displayed on the fifth screen 730 is not moved back. However,
after the combination key 790 is pushed, when the user moves back
the image displayed on the fourth screen 720 by the time t1, the
image displayed on the fifth screen 730 is also moved back by the
time t1.
[0187] When the combination key 790 is used as described above, a
captured image of the user which is displayed on the fourth screen
720 and a captured image of a comparison target which is displayed
on the fifth screen 730 may be easily repeated. Accordingly, it is
possible to easily compare/contrast the user with the comparison
target.
[0188] Meanwhile, a reference numeral 703 is an overlap key. When
the user pushes the overlap key 730, a display screen shown in FIG.
24 or 25 may be shown.
[0189] FIGS. 24 and 25 are views illustrating display screens to
which an overlap function is applied.
[0190] Referring to FIG. 24, the user image of the fourth screen
720 and the image of the other user of fifth screen 730 are
overlapped. As described above, an image formed by overlapping the
fourth screen 720 with the fifth screen 730 is provided such that
it is possible to easily and accurately see a difference in posture
between the user and the other user.
[0191] Referring to FIG. 25, the overlap images of not only the
fourth screen 720 and the fifth screen 730 but also the sixth
screen 770 and the seventh screen 780 may be provided. As described
above, an image formed by overlapping the sixth screen 770 with the
seventh screen 780 is provided such that it is possible to easily
and accurately see "a difference in movement of the center of
gravity according to a time" between the user and the other
user.
[0192] Also, on the basis of the difference in posture and a
difference in calculation values between the user and the other
user in FIGS. 24 and 25, a posture correction of the user may be
provided. In detail, through the analysis, the external device 900
or a server connected to the external device 900 may precisely
point out the differences between the user and the other user
through separate calculations and may provide a solution for
overcoming the differences.
[0193] Meanwhile, when the user pushes a screen return key 709, the
display screen may return to that shown in FIG. 22 or 23.
[0194] Although the embodiments of the present invention have been
described with reference to the attached drawings, it should be
understood by one of ordinary skill in the art that the present
invention may be implemented in other detailed forms without
changing the technical concept or essential features thereof.
Therefore, the above-described embodiments should be understood to
be exemplary and not limiting in every aspect.
